Sentence Correction

Children who watch a great deal of television (and their families have
a history of near-sightedness) will probably require glasses sooner
than their peers who are not predisposed to myopia in these ways

1.
2. whose families have a history of near-sightedness
3. and a history of near-sightedness runs in the family
4. whose families have a history of near-sightedness running in them
5. with a history of near-sightedness running in the family

is it 5?

That's what I thought but its not 5. Explanation - 5 does not correct parallel construction problem.

interesting,
to make it parallel I was looking for an 'and' before 2.
However, i don't think 1,2 and 4 can make the sentence parallel.
so I was between 3 and 5.
3 I discarded because I was looking for a 'have'
and have a history of....

anyways what is the QA?

OA is 2

OA is 2

so the sentence would be ..

Children who watch a great deal of television whose families have a history of near-sightedness will probably require glasses sooner
than their peers who are not predisposed to myopia in these ways
